Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an auxiliary mirror used for a driver to visually visually recognize a portion near a front wheel portion of an automobile.

[0002]

2. Description of the Related Art Conventionally, a so-called two-box type recreational vehicle with a door mirror is provided with an auxiliary mirror on the fender portion of the left front wheel in order to project the left front wheel portion, which is particularly difficult for the driver to confirm. Is provided.

[0003]

However, in this type of auxiliary mirror, in order to image the vicinity of the left front wheel, the mirror surface must be tilted considerably downward so that it is almost directly below the position of the auxiliary mirror. Actually, it was difficult for the driver to confirm the image near the left front wheel. On the other hand, when an image that the driver can see is projected on the mirror surface, the conventional auxiliary mirror must be placed with the mirror surface upright, and as a result, the driver can Due to the positional relationship with the person, it was inevitable to look at the rear side of the vehicle than the auxiliary mirror, specifically, the part between the left front wheel and the rear wheel.

Therefore, the technical problem to be solved by the present invention is to provide an auxiliary mirror that allows the driver to clearly see the vicinity of the front wheel portion.

[0005]

In order to solve the above technical problems, the auxiliary mirror according to the present invention is constructed as follows. That is, a prism that is located on the side of the fender portion and refracts light from the vicinity of the front wheel portion toward the front side of the vehicle body, and a reflecting mirror that is positioned above and above the prism and that reflects the transmitted light of the prism to the driver side. And a casing that holds these prisms and reflecting mirrors.

[0006]

In the above structure, the light from the vicinity of the front wheel portion passes through the prism, is once refracted forward, is reflected by the reflecting mirror, and reaches the eyes of the driver. In other words, the reflector
If you set the angle to the extent that the middle part of the front wheel and the rear wheel was projected with the conventional auxiliary mirror so that the driver can easily see the image,
For the driver, the vicinity of the front wheel portion in front of that is displayed. Therefore, according to the present invention, it is not difficult to see the mirror surface from the lateral direction, and the driver can clearly see the necessary portion from the direction closer to the front surface of the mirror surface than in the conventional case.

The auxiliary mirror having this structure may be provided not only on the left side of the vehicle body but also on the right side of the vehicle body. In this case, the effect of visually recognizing the vicinity of the right front wheel without opening the side window is obtained. Further, in order to visually recognize not only the vicinity of the front wheel portion but also other blind spots such as between the front wheel portion and the rear wheel portion, another reflecting mirror may be provided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An auxiliary mirror for an automobile according to an embodiment of the present invention shown in FIGS. 1 to 5 will be described in detail below.

FIG. 1 is a perspective view of the auxiliary mirror of the present embodiment mounted on the left fender of an automobile as seen from the front of the vehicle body, FIG. 2 is a perspective view as seen from the inside of the rear, and FIG. FIG. 4 is a schematic diagram showing the refraction of light when viewed from the side surface, and FIG. 5 is a schematic diagram showing the refraction of light when viewed from a plane.

This auxiliary mirror is located on the side of the left fender portion 10 and refracts light from the vicinity of the left front wheel portion toward the front side of the vehicle body, and is located in front of and above the prism 3 near the center of the vehicle body. , And a reflecting mirror 2 that reflects the transmitted light of the prism 3 to the driver side. The prism 3 and the reflecting mirror 2 are held by a casing 1 fixed to the left end of the bonnet 11.

The prism 3 is formed by connecting a prism portion 3a having a small triangular section in a Fresnel lens shape to form a plate shape. As shown in FIG. 5, the boundary line between the prism portions 3a is on the side surface of the vehicle body. It is arranged to incline at an angle of about 45 °. On the other hand, a convex mirror is used as the reflecting mirror 2.

The casing 1 is hollow, and the driver side portion of the front surface of the reflecting mirror 2 serves as a viewing window 1a. On the left side of the viewing window 1a, another reflecting mirror 4 is provided in order to include a portion that cannot be seen only by the door mirror 12 and the reflecting mirror 2, that is, a blind spot in the driver's view. Has been. By providing this reflecting mirror 4, the driver can visually recognize, for example, between the left front wheel portion and the rear wheel portion. Since there are individual differences in the driving position of the driver, it is preferable that the reflecting mirrors 2 and 4 be held in the casing 1 so that their angles can be adjusted.

According to the structure of this embodiment, the light from the vicinity of the left front wheel is refracted by the prism 3 and then reflected by the reflecting mirror 2 to reach the eyes of the driver as shown in each drawing. Therefore, if the reflecting mirror 2 is set to an angle that reflects the intermediate portion between the front wheel and the rear wheel with the conventional auxiliary mirror so that the driver can easily see the image, the driver can be positioned in front of the conventional auxiliary mirror with respect to the driver. The vicinity of the front wheel portion will be displayed. Therefore, according to the present invention, the driver can clearly see the vicinity of the left front wheel portion because there is no need to tilt the mirror surface downward so that an image cannot be confirmed.

Further, another reflecting mirror 4 is provided in addition to the one for the left front wheel portion, and the space between the left front wheel portion and the rear wheel portion, the left rear wheel portion, and the like can be visually recognized. If the auxiliary mirror is provided, the safety of the vehicle is greatly improved. Further, since the prism 3 is provided to refract the light toward the center of the vehicle body, it is possible to reduce the amount of projection of the reflecting mirror itself to the side of the vehicle body as compared with the case where the prism is not provided.

In this embodiment, the prism 3 is provided in order to refract light and project the lower part of the casing 1. However, instead of the prism 3, it is also effective to dispose a concave lens at a right angle to the center line C. .. By disposing the concave lens in this manner, for example, the driver can visually recognize a wide area between the front wheel portion and the rear wheel portion. Further, a concave lens or a convex lens may be added to the auxiliary mirror having the configuration of the present embodiment, or the convex mirror used for the reflecting mirror may be replaced with a concave mirror or a plane mirror so that the size of the visible region near the front wheel portion is appropriately set. Good.
